A 38-year-old male presented with a painless, indurated, mobile, and irreducible mass in the left inguinal region noted for months. Because malignancy could not be excluded from physical examination, tumor markers, ultrasonography, and computed tomography, the inguinal mass was excised completely. The pathology revealed the diagnosis of a solitary fibrous tumor (SFT), a generally benign tumor that rarely arises in the inguinal region.
A SFT is a rare mesynchymal neoplasm that may occur in a wide range of sites, more commonly in the pleura, but rarely reported in the inguinal region. Inguinal SFT can simulate an inguinal hernia. The image findings are generally nonspecific for a preoperative diagnosis. Complete surgical excision is an appropriate option for cure and confirmation of the diagnosis. The prognosis is generally satisfactory. However, long term follow-up is necessary because local recurrence and metastasis have been reported in some cases.
